The German-Polish relations have dramatically changed to the better after German unification, that this has been denoted as a miracle. Societal actors in the FRG, the GDR and Poland, who started their contacts in the early fifties, have undoubtedly contributed to this fundamental change. The contributions included describe the evolution of the relationship between the Federal Republic of Germany and Poland as well as the relationship between the German Democratic Republic and Poland at the state and the societal level until 1990, these relationships between the unified Germany and Poland after 1990. Added on to these analyses are general reflections related to the integration based upon the results of the German-Polish elite survey from 1998. Finally, the perspectives for the future of this bilateral relationship are addressed. The analyses are based upon the presentations in the scientific colloquium, Ten years after signing the good neighbourhood treaty - the German-Polish relations - a community of common interests and values?, that took place April 4, 2001, at the Science Center Berlin.
